To evaluate the gastroprotective and antioxidant effects of pretreatment with water kefir on ulcers induced HCl/ethanol. All pretreatments lasted 14 days. Male mice were separated into five groups: control (C) group received vehicle without ulcer induction; ulcerated (U) vehicle; lansoprazole (L) 30 mg/kg/day lansoprazole; (WK15 WK30) groups WK at a dose 0.15 or 0.30 ml/kg/day, respectively. Ga...

Acidic deposition, commonly referred to as acid rain, is causing serious environmental damage in eastern Canada. The revenues from forest products, tourism and sport fishing are estimated to account for about 8% of the gross national product. The impact on human health is not as clearcut and a multi-department program on the Long-Range Transport of Airborne Pollutants (LRTAP) was approved by th...

The first aim of this study was to examine which control mechanism is the most effective and profitable to control Salmonella in fattening pigs. Three treatments at farm-level are examined: 1) hygiene and management measures; 2) acidified feed; 3) acidified drinking water. The second aim of this study was to examine the correlation between the Salmonella blood titre (immunology S/P value) and t...

The hides of cattle are the source of Escherichia coli O157:H7 that contaminates beef carcasses during commercial beef processing. Therefore, effective interventions that reduce hide contamination should reduce subsequent carcass contamination. The first objective of this study was to identify the most effective reagents for decontamination of beef hides. Cattle hides draped over barrels were u...

Aluminum salt that is generally presents as a solid phase in the water purification sludge (WPS) can be dissolved, recovering a liquid phase, by adding strong acid to the sludge solution. According to the reaction kinetics, when reactant is in the form of small particles with a large specific surface area, or when the reaction temperature is high, the quantity of dissolved aluminum salt or reac...

product code, the date and time of container closure inspections, the measurements obtained, and all corrective actions taken. Records shall be signed or initialed by the container closure inspector and reviewed by management with sufficient frequency to ensure that the containers are hermetically sealed. (d) Records shall be maintained to identify the initial distribution of the finished produ...

Bovine milk proteins have a low absorption rate due to gastric acid-induced coagulation. Acidified milk remains liquid under acidic conditions; therefore, the absorption rate of its protein may differ from that of untreated milk. To investigate how this would affect muscle protein synthesis (MPS), we compared MPS after ingestion of acidified versus skim milk in rats. Male Sprague-Dawley rats sw...

BACKGROUND Pretreatment of lignocellulosic biomass is a prerequisite for effective saccharification to produce fermentable sugars. In this study, "green" solvent systems based on acidified mixtures of glycerol carbonate (GC) and glycerol were used to treat sugarcane bagasse and the roles of each solvent in deconstructing biomass were determined. RESULTS Pretreatment of sugarcane bagasse at 90...

TLA!rapid expansion of shrimp farming has resulted in extensive excavation of coastal sediments that contain pyrite (FeS2). When oxidised, pyritic sediments develop into acid sulfate soils (ASS), which are characterised by high acidity and elevated concentrations of sulfate and toxic metals (Golez 1995). ASS reduce water quality in shrimp ponds, groundwater and nearby creeks and estuaries. Cons...

A number of studies on the influence of acid on Escherichia coli O157:H7 have shown considerable strain differences, but limited information has been reported to compare the acid resistance based on the different sources of E. coli O157:H7 isolates. The purpose of this study was to determine the survival of E. coli O157:H7 strains isolated from five sources (foods, bovine carcasses, bovine fece...
